One thing that’s been bugging us, however, is the question of how K.J. Apa, who plays Archie Andrews in the show, broke his hand. The actor tweeted back in April that he’d caused himself injury while filming the season finale, and has been a bit cagey ever since.

Our finale ep is so good I can’t stop thinking about it. Not to mention I broke my hand while shooting it. Mental.

In the season finale of Riverdale we saw the gang attempt to stop Cheryl Blossom from hurting herself in Sweetwater River. After falling through the ice, Archie, Betty, Veronica, and Jughead rush to her aid, with Archie ultimately punching through the ice to save her. It’s a pretty intense scene, and you can feel the tension.

“I wasn’t really punching the ice, but I got a little bit too excited. I was punching a foam mat … [that was] sitting on the ice,” he revealed. “It was cold, so I didn’t really feel it. It wasn’t until 20 minutes after that I realized I broke my hand. I didn’t tell anyone.”

Okay, that’s some serious dedication to your craft.

The 20-year-old also spoke about that shocking end of the season finale where Archie’s father, Fred, is shot in Pop’s diner.

“The death of Fred is still unclear, but either way, it’s going to change Archie’s life forever,” Apa said. “We’re going to see a darker side to him for sure.”
